Downgrading kernel ruled out the kernel bug.

And I have tried 3 times to suspend, and can reproduce the high GPU load=
=20
3 times.

Another thing I noticed is, previous when suspending, the eGPU seems to=20
be completely shutdown (only the power LED lights up, the work LED shut=20
down).

But now when suspension happened, the eGPU doesn't shutdown at all, just=

with its fan ramping up.

Will try downgrading the firmware as the next step just in case.

Thanks,
